Why can't I join Zoom meeting with correct password?
Sign into the Zoom web portal and navigate to Settings. In the Security section, verify that the passcode settings that you would like to use for your meetings and webinars are enabled. If the setting is disabled, click the toggle to enable it. If a verification dialog displays, choose Turn On to verify the change.
